Uninstall an obsolete from another (conflicting) port

[Randall Wood]

What's the best way to do this?

I have seen calls in ports doing this in the past like:

pre-install {
	system "port -f uninstall xxx"
}

Which is not really the way to do it. Clearly the best way would be  
loop the list of versions of the port and uninstall each one using  
the MacPorts API, but given the state of the docs...
